Only show tooltips when sidebar is not open

[azrikahar]

Fixes #18253

Added a condition to ensure the tooltip only appears when the sidebar is closed. Also added the same change for Activity Log (at the bottom right corner of sidebar).

Based on other similar conditional tooltip usages such as:

• directus/app/src/components/v-text-overflow.vue

  Line 2 in ae68a6e

  <div ref="el" v-tooltip:[placement]="hasEllipsis && text" class="v-text-overflow">

• directus/app/src/modules/content/components/navigation-bookmark.vue

  Line 17 in ae68a6e

  v-tooltip.bottom="!hasPermission && t(`cannot_edit_${scope}_bookmarks`)"

• directus/app/src/modules/settings/routes/flows/components/operation.vue

  Line 37 in ae68a6e

  <v-icon v-tooltip="editMode && t('operation_handle_resolve')" name="check_circle" />
